Title (EN) ELECTROLYTES AND ELECTROCHEMICAL DEVICES
(FR) ÉLECTROLYTES ET DISPOSITIFS ÉLECTROCHIMIQUES
Abstract:
(EN) Disclosed herein are electrolytes and electrochemical devices. The electrochemical devices comprise cathodes that include nickel-rich layered lithium transition metal oxides, lithium-rich layered transition-metal oxides, lithium manganese-based spinel oxides, lithium polyanion-based compounds, and combinations thereof. The electrolytes include a lithium imide salt, an aprotic acyclic carbonate solvent, and an additive, wherein the additive comprises a metal salt, an aprotic solvent, or a combination thereof. The electrolyte can be stable at a voltage of 4.3 V or above vs. Li/Li+.
(FR) L'invention concerne des électrolytes et des dispositifs électrochimiques. Les dispositifs électrochimiques comprennent des cathodes qui comprennent des oxydes de métal de transition de lithium en couches riches en nickel, des oxydes de métal de transition en couches riches en lithium, des oxydes de spinelle à base de lithium-manganèse, des composés à base de polyanion de lithium, et des combinaisons de ceux-ci. Les électrolytes comprennent un sel d'imide de lithium, un solvant de carbonate acyclique aprotique, et un additif, l'additif comprenant un sel métallique, un solvant aprotique, ou une combinaison de ceux-ci. L'électrolyte peut être stable à une tension supérieure ou égale à 4,3 V par rapport à Li/Li+.
